Scooba® Battery

Item Number: 14904

iRobot Scooba Battery powers Scooba for two tanks of solution per charge. Get more cleaning time from your Scooba by keeping a second battery on hand and ready to go! Charge one battery in the Charging Base while Scooba is cleaning.This battery is only compatible with Scooba 300, 5900, and 5800.

I am reviewing the GREY 4100mah battery that came with the Scooba 390.

Despite the rather high price, I am completely satisfied with this battery.

I don't think others are reviewing the same battery, because I have been running this battery several times per week - for just over a year now - and it STILL lasts for at least two full tanks of cleaning solution, well over 120 minutes.

Also, I have left the battery plugged in constantly with no issue. I have to conclude that the older reviews here are for a completely different battery, maybe the old blue style, because this battery is high quality, even the plastic and decals.

Despite the harsh reviews, I felt confident enough to purchase a second battery to extend the cleaning time.

I have had my scooba for 2 years now. I was very hesitant initially about purchasing the Scooba as the reviews regarding the battery were not good. I had a feeling that the reviews that gave the battery poor performace reviews were due to user error and not a failure on the part of the product. I decided to go ahead and purchase the Scooba and for the first 18 months I used the product on a weekly basis at a minimum. I would leave it charged in at all times when not in use. Then for the last 6 months I never used it but I did leave it plugged in. I cleaned my floors the old fashion way with a mop. I then went to use the scooba and low and behold the battery didn't even last ten minutes. I removed the battery and charged it on the seperate charger and then put it back in. The charge was better but still not what it was for the first 18 months therefor I will be ordering a new battery. The moral of the story everyone is batteries, ALL BATTERIES, are not designed to be plugged in, left charging for extreme, prolonged amount of times and then used infrequently. If you plan on using the Scooba once every few months as some of the reviews on here mention, then don't buy this product. If you want to save yourself some time and have an incredibly clean floor and will use it frequently, you will not be sorry.

I see some comments on the battery failing to hold a charge after some months of use. I recently had that experience but found a way to overcome it.

The battery had gone dead after not charging it for a month. I normally leave it plugged in and charging, but had to unplug it for some home remodeling. After charging the battery for use, I found that it would power my Scooba for only 5 - 10 minutes, much shorter than the 1.5 or more tanks of water I used to get out of it. I tried a few times with the same result.

Eventually I pulled out the battery for a few minutes, then re-installed it. Then I charged it, which took 2 - 3 hours. After that its charge capacity was restored.

I don't know for sure what happened. Maybe some power management circuit was in a bad state and needed a reboot, which occurred when I removed the battery for a few minutes. Whatever, perhaps you might try that if your battery is no longer holding a charge.

Once again my Scooba batteries have pooped out. With all my experience (about 8 or 9 years)using this product, the batteries never last. I write the date of purchase on them with a permanent marker so I can track their useful life. These 2 were purchased in August of 2012. They lasted nearly a year. I keep them plugged in all the time except when being used and alternate them. When I see the quick flash, I let it charge over 24 hours before using it again. I dry very carefully and clean around the battery compartment all the time. I am sick of spending money on these batteries. I love my Roomba and Scooba, but I feel like a schmuck sending this company more of my money. I probably will put it away until I can find someone to build me a better battery.

My Scooba has been lightly used. I have maintained my Scooba as per manufacturers instructions and kept my battery on charge when not in use. The Scooba has never cleaned an entire area, NOT EVER, due to poor battery life. Today I set the robot to work in a small bedroom and the battery lasted 3 minutes ( I KID YOU NOT) after charging for 16 hours. Unfortunately, I need to purchase a new battery at $70 a pop plus whatever the shipping costs are. When the robot finally dies (which probably won't be long) I will not buy another Irobot product. I only wish that I had read the poor reviews before purchasing this expensive product. The manufacturers are clearly NOT LISTENING to their consumers.

I've had my Scooba for several years and love it. However, as has been said here over and over, the battery life is too short for a [$] item.When new the battery can power through two tanks full of cleaning fluid. However, the decline in longevity becomes apparent before too long. After a year or so, it lasts not much beyond one tank. My last battery died completely just short of two years after receipt. That's $35 per year for batteries.

Regarding the rather consistent comments about battery life, the reality is that it should never be necessary to continuously charge a rechargeable battery, ever. Although conditioning is a common need for such batteries, users having the kind of problems expressed in this forum need to recognize that 1. the company is aware of the problem, 2. the company profits from battery replacement just like printer companies profit from ink, 3. if the company thought something should be done, they would have done something by now. A good company always listens and responds to its customers, especially when it comes to quality control. No excuses.
